Stuffed marrows

We have a large number of marrows from recent swaps. Most will be used to make chutneys but some will be used fresh. Tonight I used up a load of vegetables that had seen better days but which I did not want wasted to make a stuffing for a baked marrow. Ingredients included tomatoes, celery, sage, onion, garlic, breadcrumbs and a bit of oil, black pepper and salt. Cook in the oven for half an hour. I set the temperature at 180C but I think 200C would have been better.
